Update Seed Tube
13. Remove and save the seed tube gasket (9).
NOTE:
If the planter has Row-Pro™ servo down-pressure,
several rows have an extra cable from load cell to harness
that routes through the gasket. It is not possible to
completely remove the gasket on these rows. Slide the
gasket up out of the way.
14. Pull the old seed tube up and out of the opener
shank. Be careful to not damage the extra cable on
rows with Row-Pro™ load cells. The seed sensor
(10) and its cable, and seed tube hook clip (11) will
come out with the seed tube.
15. Note how the sensor is aligned on the tube. Cut the
cable ties securing the seed sensor to the seed tube.
Remove and save the sensor components.
16. Remove and save the seed tube hook clip.
17. Discard the seed tube.
NOTE:
Older seed tubes do not support detection (including
blockage detection) of very small seeds.
18. Select one
:
19. Clean and dry the face (14) of the sensor receiver.
This may require carefully removing existing silicone
sealant. Clean and dry the front face of the sensor
locating ring (15) on the new tube.
20. Apply a generous dab of clear silicone sealant to the
front (outside) face (15) of the sensor locating ring.
Avoid introducing any air bubbles.
21. Attach the saved seed sensor to the new seed tube.
Secure with new ties.
22. Snap the saved seed tube hook clip on the new seed
tube. Verify that the rear center hole in the clip is
over the alignment stud on the seed tube.
23. Insert the new seed tube assembly into the shank.
Take care not to snag any Row-Pro™ load cell cable
present. Note that a lower hook on the seed tube
hook clip needs to engage a pin (17).
24. Secure seed tube with clevis pin (5) and cotter.
25. Re-install the saved seed tube gasket.
26. Swing meter assembly back into position. Secure
with the four bolts.
